A few years ago, Facebook was forced to retreat from a new service called Beacon. It tracked what the social network"s users were doing elsewhere on the web—which caused a huge 1 because of the loss of personal privacy. 2 , Facebook promised to make 3 efforts to better protect people"s information.But 4 the firm has not been trying very hard. On November 29th America"s Federal Trade Commission (FTC) 5 the results of an investigation it had conducted of Facebook. They showed that the world"s biggest social network, which now 6 more than 800m users, has been making information public that it had 7 to keep private.The FTC"s findings come at a(n) 8 time for Facebook, which is preparing for an initial public offering (IPO) that is almost 9 to take place next year. Some recent reports have 10 that the firm may seek a listing as early as next spring, and that it will try to 11 a whopping $10 billion in an IPO that would 12 it at $100 billion. To 13 the way for an offering, Facebook 14 needs to resolve some of the regulatory tussles over privacy that it has become embroiled in. 15 the FTC"s announcement, which came as part of a settlement struck between the commission and Facebook. The FTC"s investigation 16 a litany of instances in which the social network had 17 its users. In what is perhaps the most damning of the findings, the agency documents that Facebook has been 18 people"s personal information with advertisers—a practice its senior executives have 19 sworn it does not indulge in. The FTC also says that the firm failed to make photos and videos on deactivated and deleted user accounts 20 after promising to do so.

Recalculating the global use of phosphorus, an important fertilizer element of modem agriculture, a team of researchers warns that the world"s stocks may soon be in short supply and that overuse in the industrialized world has become a leading cause of the pollution of lakes, rivers and streams,Writing in the Feb. 14 edition of the journalEnvironmental Research Letters, Stephen Carpenter of the University of Wisconsin-Madison and Elena Bennett of McGill University report that the human use of phosphorus, primarily in the industrialized world, is causing the widespread eutrophication of fresh surface water. What"s more, the minable global stocks of phosphorus are concentrated in just a few countries and are in decline, posing the risk of global shortages within the next 20 years. "There is a finite amount of phosphorus in the world," says Carpenter, one of the world"s leading authorities on lakes and streams. "This is a material that"s becoming rarer and we need to use it more efficiently."Phosphorus is an essential element for life. Living organisms, including humans, have small amounts and the element is crucial for driving the energetic processes of cells. In agriculture, phosphorus mined from ancient marine deposits is widely used to boost crop yields. The element also has other industrial uses.But excess phosphorus from fertilizer that washes from farm fields and suburban lawns into lakes and streams is the primary cause of the algae blooms that destroy freshwater ecosystems and degrade water quality. Phosphorus pollution poses a risk to fish and other water life as well as to the animals and humans who depend on clean fresh water. In some instances, excess phosphorus sparks blooms of toxic algae, which pose a direct threat to human and animal life."If you have too much phosphorus, you get eutrophication," explains Carpenter, of the cycle of excessive plant and algae growth that significantly degrades bodies of fresh water. "Phosphorus stimulates the growth of algae and weeds near shore and some of the algae can contain cyanobacteria, which are toxic. You lose fish. You lose water quality for drinking." The fertilizer-fueled algae blooms themselves amplify the problem as the algae die and release accumulated phosphorus back into the water.Complicating the problem, says Carpenter, is the fact that excess phosphorus in the environment is a problem primarily in the industrialized world, mainly Europe, North America and parts of Asia. In other parts of the world, notably Africa and Australia, soils are phosphorus poor, creating a stark imbalance. Ironically, soils in places like North America, where fertilizers with phosphorus are most commonly applied, are already loaded with the element. Bennett and Carpenter argue that agriculture practices to better conserve phosphate within agricultural ecosystems are necessary to avert the widespread pollution of surface waters. Phosphorus from parts of the world where the element is abundant, they say, can be moved to phosphorus deficient regions of the world by extracting phosphorus from manure, for example, using manure digesters. Which of the following is not correct about the use of phosphorus
It"s not that we thought things were free. It"s just that this year there were no fixes to the messes we made—no underwater oil-well caps, no AIG bailouts, no reuniting the island castaways in a church and sending them to heaven. We had to idly watch things completely fall apart, making us feel so pathetic that planking seemed like a cool thing to do. This was the year of the meltdown.If a meltdown could happen at a nuclear reactor in Japan—a country so obsessed with keeping up to date that its citizens annually get new cell phones and a new Prime Minister—we should have known we were all doomed. Meltdowns happened to the most unlikely victims. Everyone was so vulnerable to meltdowns that even Canadians rioted, though they did it only so the rest of the world wouldn"t feel bad about their riots.It didn"t take a tsunami; anything could trigger a meltdown. Greece, a country so economically insignificant that its biggest global financial contribution to this century was that Nia Vardalos movie, sent the entire European economy into a meltdown. A meltdown of both the U.S. credit rating and Congress"s approval rating was unleashed over raising the debt ceiling, something so routine and boring. Sometimes, it didn"t take an actual sexual affair to ruin your promising political career.Sometimes, crises sprang out of tiny mistakes that usually have no consequences whatsoever, like that day in college when you went to a protest, charged a couple more things on your nearly maxed-out credit card and drunkenly told the pizza guy with all the dumb ideas that he should totally run for President. Well, when the entire country does that at once, you get a meltdown.There was even a meltdown of the once powerful American middle class. A year ago ours was still a country that pretended there was no class system, where rich people all called themselves "upper-middle class". Now we are full-on feudal, with an angry 99% and a 1% who actually understand the things which the 99% are inarticulately complaining about. The meltdown itself melted down when Occupy Wall Street protesters and police couldn"t agree on lawn care.It"s too late to cool the rods. We are either going to abandon the old structures altogether—nuclear power, the euro, Arab secular rule, unregulated capitalism—or wait a really long time for things to get better. We are finally going to have to choose between our modem love of constant drama and our modem laziness. I know which I"m betting on. Laziness has a really high melting point. What do the 1% people know according to Paragraph 5
